I have a 6+. Somehow I must have deleted a couple of apps from my phone’s desktop. I don’t know what they all are but I do know one. I went to the AppStore, found it and opened it. But it doesn’t mount on my desk or the list of icons. How do I get it back? So this means I have to go to the store every time I want to open it? Or scroll through the open apps? I hope this makes sense.
